Salt stress-induced pH-changes in roots cells (hairy zone near the hypocotyl) of Arabidopsis expressing Pt-GFP. Roots were perifused with unbuffered standard medium (SM = KCl, CaCl2, MgCl2 - 0.1 mM each) and millimolar NaCl concentrations as indicated by the top bar of the graph. Given is the average of 5 from 4 individual experiments. Error bars indicate standard deviations.
